在储存同品种油的一组卧式金属油罐上,用一根同口径的管线串联安装三个呼吸阀。既节省了设备(相对每个油罐上安装呼吸阀),又减少油品损耗。因为实际操作时,一部分罐发油时,罐需要吸气,而其他油罐当温升时,蒸气压大于10000mmH_2O又要呼气(油蒸气)。卸收油时也存在有的罐需
On a set of horizontal metal tanks containing the same type of oil, install three breathing valves in series with a pipe of the same caliber. Saving equipment (relative to each tank mounted breathing valve), but also reduce oil loss. Because in actual operation, some of the tank oil, the tank needs inhalation, while the other tank when the temperature rise, the vapor pressure greater than 10000mmH_2O also exhale (oil vapor). Unloading oil when there are some tank needs
